Having recently bought some WS2812 LEDs I'm very happy with the software and controlling them. But is there a way to tell the software how many LEDs are on your strip? The default for the JRainbow header is 20, and its annoying because with my high density strip that means every 15 or so cm, the effect repeats itself. I want to specify the number of LEDs so that the effect can utilize all the LEDs instead of just repeating.
